OIL-BURNER.

Specification of IlLetters Patent. Patented Sept, 26, 1 911.

Application filed October 25. 1909, Serial No. 524,425. Renewed February20, 1911.' Serial No. 609,788.

To all whom it may concern:

Be it known that l, Wrumnr D. Dawson, a citizen of the United States,residing at Mangum, in the county of Greer and State 5 of Oklahoma, haveinvented certain new and useful Tmprovements in Oil-Burners; and I. dodeclare the following to he a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it.HPINIitlillS to make and use the same.

This invention relates to improvements in oil burners. I

One object of the'invention is to provide an oil burner having animproved construction of vaporizing and discharging nozzle by means ofwhich the fuel is mixed and injected into thefire box of a stove inproper condition for burning freely without smoke or soot.

Another object is to provide means for generating and supplying steam tothe burner for the purpose of vaporizing the oil and forming the fuel.

With these and other objects in'view, the invention consists of certainnovel features of construction, combination and arrangement of parts aswill be more fully described and particularly pointed out in theappended claim.

In the accompanying drawings: Figure 1 is a vertical sectional viewthrough the fire box of a. cook stove illustrating theinvcntion appliedthereto andshowing in full lines the arrangement of the oil tank whenoil is fed by gravity and in dotted lines. the arrangement of the tankwhen the oil is fed by pressure. Fig. 2 is a similar view illustratingthe application of the invention to a heating stove and showing indotted lines the manner in which the tank may be arranged outside of thehouse and the oil. fed either by gravity or by air pressure. Fig. 3 isan end view of the burner nozzle. Fig. 4 is a vertical section of thesame on the line 4-4 of Fig. 3. Fig. 5 is a horizon-- tal section onthe. line 5-5 of Fig. 3. Fig. 6 is. a perspective View of the burnerreceiving'attachm'ent em ploycd in the door opening of a. heating stove.

Referring more particularly to the drawings, 1. denotes the burnernozzle which consists of a substantially triangular block or castinghaving formed on one'edge an in teriorly threaded socket 2, whichcommunicates with an obli ucly disposed steam assage 3, formed in headjacent portion 0 the nozzle and extending through from the upper tothe lower end of the same. The upper open end of the passage 3, isthreaded to 6-3 receive a closingplug 4, which is adapted to be removedto permit the passage 3, to be readily cleaned out when necessar On oneside of the nozzle at its upper en is formed an offset or projectingportion in which is arranged a horizontal oil passage 5, whichcommunicates at. one end with a threaded nipple 6, formed at the end ofthe offset or projecting portion. At its opposite end the passage 5,communicates with a vertically disposed passage 7, formed in thcnozzleat the opposite side of the same from the steam passage The passages 3and 7 come together at the lower end of the nozzle as shown. The upperend of the vertical 76 portion 7 of the oil passage extends through thetop of the nozzle and is threaded to receive a closing plug 8, which isadapted to s be removed to permit the passage 7, to be readily cleaned.Adapted to be screwed on to the lower end of the nozzleand over themeeting ends of the passages 3 and 7, is a spray. tip 9, in which isformed a mixing chamber 10,' wherein the oil and steam are thoroughlymixed before being discharged through the opening in the tip. \Vith thesocket 2, of the passage 3, is adapted to be connected a steamsupplypipe 11, which is connected to a super-heating steam pipe 12,which, in turn, is connected to a. boiler 13. adapted to be arranged. inthe fire box of a stove. The boiler 13, is connected to a water supplypipe 14, having arranged therein a valve-1 5. The water 96. supply pipemay be connected with a water system or with a. water supply tank 16, asshown in the drawings. When the water supply pipe is connected with awater systcm, T preferably provide the boiler with a 0 safety valve 17,which is shown in Fig. 2,

of the drawings, and is connected to the boiler by a steam pipe 18. 1

To the socket 6, of the oil passage 5, is connected an oil-supply pipe19. having arranged therein avalve 20. The pipe 19, may be'conncetedwith an oil tank 21, arranged at a suitable elevation above the nozzleeither within the house. as shown in full lines in Fig. 2, of thedrawings, or outside 11.)

of the" house as shown in dotted lines in Fig.

2, of the' drawings,-v whereby the oil is fed by gravityto the nozzle.If desired, the oil may be fed to the nozzle under pressure and whenthus supplied, the pipe'19, is connected' to the pressure tank 22, asshown in dotted lines in 1 and 2, of the drawings, and which may bearranged within or outside of the house at any desiredlocation.

The pressure tank 22, is provided with a suitable filling openingclosedby a cap 23, and is also provided with a nipple 24, for theattachment of an air pump whereby ai is forced into the tank to causethe discharge of the oil therefrom.

When the burner is applied to a cook stove, a right angularly formed boxor casting 28, is provided, said box being adapted to be set into thedoor opening of the stove and to be detachably secured in any suitablemanner. In the bottom plate of the box 28, is. formed an opening 29,through which the nozzle and the water and steam conducting pipes pass.The boiler in this instance,

is arranged on a tray of broken stone or the like set on torthe grate ofthe stove as shown.

When using'the burner, a small quantity of oil is permitted to dischargefrom the nozzle and on to the tray of broken stone .arranged on thegrate of the stoves and said oil ,is ignited. The flame of the burningoil in the tray of stone primarily heats the water in the boiler andgenerates sufficient steam to mix with the oil. in the mixing chamberandto spray the same therefrom in the form of fuel which is ignited atthe burner tip and blazes down on to the boiler.

; witnesses.

nooessa When the boiler is connectedwith a water" supply tank, the .feedof the water to the boiler will be regulated by the amount of backpressure of the steam in the boiler, thus automatically controlling thesteam supply and consequently the flame of the burner.

From the foregoing description taken in ings, the construction andoperation of the invention will be readily understood without requiringa more extended explanation.

Various changes in. the form proportion and the minor details "ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention defined in theappended claims. I

, Having thus described my invention, what I claim is:

In a burner for stoves, a nozzle provided with a pair of'longitudinalsteam and oil passages extending through the'top of the nozzle andconverging together at their lower ends, saidnozzle also having a pairof '5: connection with the accompanying draw-- hollow interiorlythreaded oflset portions communicating, respectively, with the steamandoil passages of the nozzle, removable plugs screwing in the upperends-of said passages, a mixing and spraying tip screwing on the lowerend of the nozzle and cornmunica'ting with said oil and steam passages,a boiler adapted to be arranged in the fire box of the stove, a steampipe between the boiler and the offset portion of the nozzlecommunicating with the steam passage of the nozzle, an oil supply pipecommunieating with the other-offset portion of the nozzle, a source ofwater and a supply pipe between said source and the boiler.

. In testimony whereof I have hereunto set my hand in presence of twosubscribing NVILLIAM I). DA'WSON.
